A volunteer student project built for the EPFL community.
Access is restricted to @epfl.ch addresses to keep exchanges local and trusted.
Each reused textbook helps avoid unnecessary printing.
A textbook has a real footprint in CO2, water and paper. Reuse is a concrete action.
No commission, no ads, no hidden fees.
The project is currently free and run on a volunteer basis.
Restricted access, strict headers, anti-bot checks and moderation.
You can delete your account and data at any time.
Meet on campus, no shipping required.
Most exchanges happen in minutes around Rolex, BC, CO and the library.
We build features that solve real student needs.
Safety and reliability come before scale.
No unnecessary data collection and no advertising tracking.
We clearly state what PolyMarket does and does not do.
No hidden monetization through user data.
Design choices prioritize usability and clarity.
